Patented July 15, 1941 UNITED STATES PATENT OFFICE WEATHER STRIP CharlesA. Hanington, Freeport, N. Y. 7

Application October 24, 1939, Serial No. 300,902 (01. 20-69) 1 Claim.

This invention relates to weather strips and in particular to a typethat can be attached to doors or windows with a minimum of effort,without the use of metallic fastening means and which can be readilyremoved as desired.

Weather stripping of the kind employed on the outer or inner surfaces ofsash frames as distinguished from the metallic weather strips embeddedin the sash frames has heretofore been tacked or nailed along one edgeto the sash frame or window and so arranged that the opposite edgeengages the moving part of the window structure. The use of metallicfastening means is objectionable because they mutilate the weatherstrip, do not hold it at all points securely against the supportingsurface and consequently permit the entrance of cold air. In order toovercome the objectionable features encountered, I have provided awindow sealing strip that employs a felt, leather, rubber or othersuitable material and which is provided directly with a zone of adhesivethat is pressure sensitive, that remains adhesive, such for instance aslatex and which permits the proper fitting of the strip to the window,allows removal thereof without marring the sash frame and also permitsthe use of the strip in connection with metallic window constructions.

A still further object of the invention is to provide a package for theweather strip, due to the fact that the pressure sensitive fasteningmeans must be kept from contacting with the strip itself when the latteris folded in a package. To this end I have provided a package having aninside surface to which the weather stripping may be secured, thesurface being waxed, non-fibrous or otherwise treated so that theweather stripping, while being temporarily held in position in thepackage, can be readily removed for use without impairing thestickingguality of the adhesive. The package is alsoi' of simpleconstruction, as is the weather stripping so that it can be sold atsmall cost.

Still further objects of the invention are the provision of reinforcingmeans in the weather strip, and the placing of the adhesive in welldefined zones.

Changes and variations may be made in the constructions shown anddescribed without departing from the principles of the invention orsacrificing its chief advantages; hence such invention is not to berestricted to the precise structures shown in the drawing, in which:

Figure 1 is a side edge view of a package in which weather strippingforming the subject of my invention is encased,

Figure 2 is a plan view of 'said package,

Figure 3 isan enlarged section on theline 3-3 of Figure 1 showing themethod of attaching th Weatherstrip within the package,

Figure 4 is a view in perspective of an end'of a piece of weatherstripping as made in accordance with my invention,

Figure 5 is a diagrammatic view showing the position the strip occupieson the sash,

Figure 6 and Figure 8 are each plan views of methods of placing theadhesive zone on the strip,

Figures '7 and 9 are end views of the strips shown in Figures 6 and 8,respectively, and

Figure 101s a plan view of a strip having the adhesive applied theretoin the nature of a zone of spots.

Referring to the drawing in detail, [0 indicates, in all of the figures,the weather strip which may be of any suitable material such as felt,rubber, leather or the like and which is long and narrow and is sold instrips of suitable length so that it can be cut to fit any window.

The strip I 0 is provided on one face with a zone of adhesive materialwhich is pressure sensitive, such as latex which is non-drying andretains its adhesive character after repeated use. As seen in Figures 8and 4, this zone of adhesive II is located inwardly from one edge ofstrip [0, while as seen in Figure 6, it begins at the edge of the stripand extends inwardly. The function of the adhesive zone I i is to securethe weather strip III to the sash frame I! so that the strip will bearagainst the window frame l3 and effectively seal the joint between thewindow and the sash frame against the weather, as shown in Figure 5.

In Figures 6 and 8, the felt strip is illustrated as having rows ofstitching I 4 and I5 alongside both edges for the purpose of providing areinforcement to prevent fraying of'the strip and to prevent endwisedistortion of the strip as it is drawn away from a holding surface. InFigure .8, the zone of adhesive H does not cover one line weather stripII and adhesive zone, as the adhesive is non-drying the weather stripsin any form illustrated may be readily removed in the spring andreplaced in the fall, being stored meantime in the original packagewhich contains the strips as sold. This package as illustrated inFigures 1 and 2 consists of a folder 2. of heavy paper or the like whoseinner surface II is waxed, or calendered or non-fibrous so that theadhesive I i' of the weather strip ll holds the latter securely in rowsin the folder andpermits said strips to be readily removed for use orreplaced for storage. The outer surface of the folder may be used forprinting and the folder may be of any size depending upon the yardage ofweather stripping contained therein. In the package, the adhesivesurface of the weather strips is thus engaged with the surface of thepackage and no sticking of one weather strip with another is possible.The adhesive eliminates the necessity of employing any other securingmeans such as nails, glue or fasteners.

'lhe reason for having the adhesive zone on one side of the strip only,is to permit the sash to be raised or lowered at will and still keep theframe and the sash. If the entire surface was covered with adhesive, itwould bind the sash and frame and prevent free raising or lowering ofthe window.

While I have illustrated and described my invention with some degree ofparticularity. I realize that in practice various alterations thereinmay be made without departing from the spirit 'of the invention or thescope of the appended claim.

What I claim is:

A Weatherstrip comprising an elongated strip of air resistant materialpresenting sides and edges, reinforcing lines of stitching extendingstrip pressing arcoss the crack between the g5 lengthwise of the stripand disposed in the sides thereof adjacent said edges, a relativelynarrow zone of pressure sensitive adhesive on one side of the stripextending lengthwise thereof and covering a line of said stitching andimpregnatmg said strip material and stitching, and the non-adhesiveportion of said side constituting a draft resisting surface.
